The Collégiale Saint-Étienne is a Gothic building in Hombourg-Haut. After the establishment of the Chapter of the collegiate by James of Lorraine, bishop of Metz in 1254, the church was erected during the 13th-14th centuries. It probably replaced an earlier church.
Although it was damaged by a fire in 1632, it was spared from destruction during the Thirty Years War and the 1789 revolution.
1847 a new organ was installed by Pierre Rivinach. In 1906 the instrument was extended by the Dalstein-Haerpfer company. In 1992 it was restored by the organ builder Michel Gaillard (Aubertin).
The stained glass windows include works by the 20th century master glass maker Jean-Henri Couturat, second 1925 Prix de Rome.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
